What Medicare edits apply to Z22.7?

The Medicare Code Editor screens inpatient claims before they are grouped. These edits name Z22.7 directly.

Cannot be a principal diagnosis — MCE edit 9

CMS will reject this code as the principal diagnosis on an inpatient claim. It describes something other than the condition chiefly responsible for the admission.

Which MS-DRGs does Z22.7 group to?

Z22.7 sits in MDC 23 and helps define the logic of 1 MS-DRG (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

How is Z22.7 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to Z22.7. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • LTBI (latent tuberculosis infection)
  • Tuberculosis, tubercular, tuberculous › latent (calcification) (calcified) (caseous) (chromogenic acid-fast bacilli) (degeneration) (fibrocaseous) (fistula) (interstitial) (isolated circumscribed lesions) (necrosis) (parenchymatous) (ulcerative)
  • Infection, infected, infective › tuberculous › latent (opportunistic)
  • Tuberculosis, tubercular, tuberculous › abscess › latent (calcification) (calcified) (caseous) (chromogenic acid-fast bacilli) (degeneration) (fibrocaseous) (fistula) (interstitial) (isolated circumscribed lesions) (necrosis) (parenchymatous) (ulcerative)

Excludes1 — never code together

The conditions below can never be reported together with Z22.7 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • nonspecific reaction to cell mediated immunity measurement of gamma interferon antigen response without active tuberculosis (R76.12)
  • nonspecific reaction to tuberculin skin test without active tuberculosis (R76.11)

Inclusion terms

Alternative wording in documentation that is classified to Z22.7.

  • Latent tuberculosis infection (LTBI)

Excludes2 — not included here — inherited from Z22

The conditions below are not part of Z22.7, but a patient may have both at the same time. When documentation supports it, Z22.7 and the excluded code may both be reported.

  • carrier of viral hepatitis (B18.-)

How long has Z22.7 existed?

Z22.7 first appears in FY2021 (FY2020 is not available, so it may have appeared then).

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
